SKATE OR TOOL HOLDER FOR GRlNDlNG-NIACHINES.

SPECIFICATION forming part of Letters Patent No. 782,278, dated February 14, 1905. Application filed April I5, 1904i Serial No. 203,280.

To all [wit/fm, 'llt Ntfty/ concern:

Be it known that I, MvRoN B. Russ, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Skate or Tool Holders for Grinding- Machines, of which the following' is a specifiration.

This invention relates to skate and tool holders for grinding-machines, and has for its object to produce a device for holdingaskate or tool in such relation to a grinding-wheel that the skate-runner or the tool can be easily and quickly and evenly sharpened.

A further object is to produce a device of this character which can be used in connection with any type of grinding-machine and when not in use can be disposed inoperatively with relation to the grinding-wheel to permit the latter to be used for other purposes.

lVith these general objects in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying' drawings, in which- Figure I is a side elevation, broken away and partly in section, of a skate and tool holding' device in operative relation to a grindingwheel. Fig'. 2 isa vertical cross-section taken on the line II .II of Fig. l, but on a larger scale. Fig. 3 is a horizontal section taken on the line III III of Fig. 2. Fig. et is a central longitudinal section taken on the line IV IV of Fig. 3.

In the said drawings, I designates a suitable frame, of skeleton construction by preference and provided at its side margins with upwardly-projecting ears 2 and at its front end with an upwardly-projecting jaw, the jaw being also of skeleton form and composed of a series of lug's 3. At its rear end the frame is provided with a concave leg-rest 4 and forward and inward of ears 2 with a pair of lugs Just forward of leg-rest 4 is an upwardlyprojecting' post 6, having' a cavity T in its upper end, and forward of said post is a boss 8 for a purpose which hereinafter appears.

A second frame, 9, also of skeleton construction by preference, is provided with depending lugs pivotally connected to lugs 5 by a cross-bolt 1l. At its front end frame 9 is provided with a depending' skeleton jaw l2 to oppose jaw 3 and rearward of pivot ll with a slot I3 and a threaded passag'e 14, carrying' a clamping-bolt l5, having its lower end engaging the cavity T of post the arrangement being such that the operation of bolt l5 will cause frames l and 9 to move their jaws 3 and 1Q, respectively, toward or from each other, so as to clamp tightly between them, as shown by dotted lines in Fig. 1, the runner of a skate, the bottom of the runner being' disposed forward of said jaws and the body of the skate between the frames and the lugs and `iaws thereof.

I6 designates a headed bolt extending through ears 2, and I7 a tap engaging' said bolt and in connection with the head thereof holding reliably upon the bolt the heads 18 of bolts It), said bolts extendingl up through the arms of the inverted-T-shaped frame 20, nuts 2l engaging the bolts at opposite sides of said frame Q0, so as to hold the vise,7 as the skate-holding frames l and E) are hereinafter termed, at the desired distance below said frame 20. 'Ihe stem 22 of the inverted-T frame is preferably tubular and near its upper end is provided witha rearwardly-projecting boss 2B, said boss being zu'ljustably connected with boss 8 by an adjustable brace constructed as follows: QI is a turnbuekle eng'aging' a bolt Q5, secured upon boss 8 by screw-boltQG. The turnbuckle also engages oppositely-threaded bolt 27, secured to boss 23 by screw-bolt 28, the arrangement being' such that the lengthening or shortening' of the brace by the rotation of the turnbuckle results in vertically adjusting' the front portion of the vise, and therefore the skate-rimner. 29 is a set-screw carried by the inverted-T frame 2O and securing' the same adjustably upon the lower end of a rod 30, which rod may be a single piece, as shown, or composed of several pieces, if dcsired. The upper end of the rod is screwed into a cap 3l, provided with a central hole 32, through which loosely extends a bolt 33, engaged within the cap by a nut BI, the upper end of the bolt terminating in a hook or eye IOO 35, engaging the eye of an eyebolt 36, screwed into a suitable timber or other support 37, the construction being such as to permit the skateholder at the lower end of rod 30 to be given a swivel movement1 whereincap 31 turns on bolt 33, or a swinging movement in any direction, the swinging movement being' from the hook-and-eye connection 35 and 36.

In practice the skate-runner 38 is clamped between the jaws of the vise by means of screw 15 and bearing-post 6, as shown in Fig. 1. The grinding-wheel 39, adapted to be driven by the usual mechanism (not shown) and provided with a radial mark 40, is now disposed with said mark toward the skate and extend-` ing horizontally, so that the operator can see at a glance whether the longitudinal center of `the skate-runner registers with the said indieating-mark. If it is materially below or above said mark, the holding device can be bodily raised or lowered by adjustment of the T-frame on rod 30. If but slightly out of alinement, it is preferably disposed in the proper position by the adjustment of the turnbuckle, which results in shortening the brace, of which it forms a part, and in turning the vise upon pivot-rod 16, so as toraise or lower the front end of the vise, and therefore the runner. For a very Eine vertical adjustment of the vise or for'an adjustment of one side of the sanne independent of the other, so as to raise or lower one end of the skate-runner, the nuts 21 are manipulated properly to raise or lower the bolts engaged thereby, the slight adjustment thus effected being permitted by the centrally-disposed brace, as will be readily understood. It will be seen, therefore, by this arrangement that the skate-runner can be easily and quickly so disposed with relation to the grinding-machine that it can be ground evenly from one end to the other.

The practical manipulation of the device in sharpening a skate is as follows: The screw l5 is turned to open the jaws 3 and 12 sufiicient to admit the runner of the skate when the latter is turned sidewise, and then the manipulation of said screw is reversed to clamp the skate-runner tightly between said jaws. The proper adjustments to dispose the runner horizontally and in the same horizontal plane as the axis of the grinding-wheel are then made. The operator then presses his leg against the rest 4 so as to press the runner with the required force against the grinding-wheel, and at the same time he swings the device laterally, so that the runner shall be operated upon for its entire length, and in said lateral movement the device is also turned slightly to accommodate the curve of the base of the runner, the swivel connection at the top of the suspended rod permitting this action to occur, it being also noted in this connection that by having the suspending-rod of suflicient length the movement of the skate will be in a substantially straight line, so that the grindingsurface shall be practically uniform for its entire length. It will thus beseen that a skaterunner of any configuration can be easily, quickly, and accurately sharpened and that the form of the grinding-wheel will determine whether or not the runner is to be hollowground. Then the device is not in use, it can be swung aside and held by any suitable means out of the way of one desiring to use the grinding-machine for ordinary purposes. For holding tools such as plane-bits and flat tools the lower frame of the vise is provided with a slot 41 and with one or more clamping-screws 4:2 to bind upon and hold the tool or plane-bit extending through said slot at substantially the angle shown in Fig. 1. rEhe upper frame of the vise and the screw 15 are of course functionless when sharpening tools supported only by the lower frame; but in other respects the device is manipulated as hereinbefore explained for the purpose of securing the tool in the desired relation to the grinding-wheel.

From the above description it will be apparent that I have produced a skate and tool holding device which embodies the features of advantage enumerated as desirable, and while I have shown the same as suspended it will be readily understood that the rod 30 might be arranged to operate horizontally or its pivoted and swiveled end be disposed below instead of above the vise. It will furthermore b e apparent that various changes as rcgards the form, proportion, detail construction, and. arrangements of the parts may be made without departing from the essential spirit and scope or sacrificing any of its advantag'es.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is4
